Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Changes in the average number of hot flashes per day* as percentages according to data from the patient diary after 84 days (3 cycles) since the initiation of treatment compared to baseline (Visit 0). | 84 days |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The change in the total score on the Greene Climacteric Scale at the end of the therapy (364 days) compared to baseline. | 364 days | This scale includes 21 symptom-questions to assess the emotional-mental state (questions 1-11), somatic manifestations (questions 12 to 18), vasomotor status (questions 19 and 20) and sexual status (21 questions). There are 4 answer options for each question, as in the assessment of the Kupperman index: symptoms do not bother at all - 0 points, slightly bother - 1 point, bother quite strongly - 2 points, extremely pronounced - 3 points. Indicators characteristic of the presence of anxiety or depression - 10 points or more, scored in the first 11 questions. The presence of somatic disorders - 6 or more points in 12-18 questions. Violation of vasomotor function - 4 or more points in 19 and 20 questions. |
| The frequency of hot flashes after 84 days since the initiation of treatment. | 84 days | — |
| Changes in the intensity of of menopausal symptoms calculated using the Menopause Rating Scale (MRS) after 84, 168, and 364 days since the treatment initiation compared to baseline (Visit 0). | 84 days, 168 days, 364 days | The questionnaire has 11 items and option to check one of 5 degrees of severity of symptoms (from 0 (none) to 5 (very severe) points at the questionnaire). |
| Changes according to the Greene Climacteric Scale in each of the 4 subscales after 84, 168, and 364 days since the initiation of treatment compared to baseline (Visit 0). | 84 days, 168 days, 364 days | This scale includes 21 symptom-questions to assess the emotional-mental state (questions 1-11), somatic manifestations (questions 12 to 18), vasomotor status (questions 19 and 20) and sexual status (21 questions). There are 4 answer options for each question, as in the assessment of the Kupperman index: symptoms do not bother at all - 0 points, slightly bother - 1 point, bother quite strongly - 2 points, extremely pronounced - 3 points. Indicators characteristic of the presence of anxiety or depression - 10 points or more, scored in the first 11 questions. The presence of somatic disorders - 6 or more points in 12-18 questions. Violation of vasomotor function - 4 or more points in 19 and 20 questions. |
| The average treatment satisfaction score according to the Likert Scale after 84, 168, and 364 days since the initiation of treatment. | 84 days, 168 days, 364 days | Assessment of satisfaction with treatment is based on the patient's assessment of the degree of his consent or disagreement with the statements in a hierarchical sequence from completely disagree through disagree, find it difficult to answer, agree to completely agree. |
| Changes according to the Hot Flush Related Daily Interference Scale (HFRDIS) after 84, 168, and 364 days since the initiation of treatment compared to baseline (Visit 0). | 84 days, 168 days, 364 days | The HFRDIS is 10-item scale measuring the degree hot flashes interfere with nine daily activities. |
| Changes in the waist circumference after 364 days of treatment compared to baseline (Visit 0). | 364 days | — |
